    Study Notes

    Etiology and Pathophysiology of Intracerebral Hemorrhage

    • Most common cause: Hypertension leads to sustained high blood pressure, causing vessel rupture due to shear stress.
    • Subtypes: Non-traumatic and traumatic intracerebral hemorrhage; focus on non-traumatic causes.
    • Common locations for hypertensive bleeds:
      • Basal ganglia (includes internal capsule, putamen, globus pallidus, caudate nucleus, thalamus)
      • Pons
      • Cerebellum
      • Least common: Cortical or lobar areas (frontal, parietal, occipital, temporal lobes).
    • Cerebral Amyloid Angiopathy: Associated with elderly patients, particularly those over 60. It involves deposition of amyloid proteins weakening vessels, leading to cortical bleeds.
    • Coagulopathies: Result from medications like anticoagulants (e.g., warfarin, heparin) or liver dysfunction, reducing the ability to form clots.
    • Hemorrhagic Transformation: Ischemic strokes can turn hemorrhagic due to treatment with tPA or increased blood pressure into previously damaged areas.
    • Malignancy: Metastatic cancers (e.g., lung, renal, melanoma, papillary thyroid) can disrupt the blood-brain barrier, leading to hemorrhage.
    • Cerebral Venous Sinus Thrombosis (CVST): A clot in brain veins can cause hemorrhage due to pressure buildup, typically associated with hypercoagulable conditions.
    • Vascular Abnormalities: Arteriovenous malformations (AVMs) and mycotic aneurysms can lead to intracerebral hemorrhages, often observed in younger patients.

    Clinical Features

    • Common symptoms:
      • Headaches, especially with cortical or lobar bleeds due to meningeal irritation.
      • Focal neurological deficits such as aphasia and weakness, analogous to ischemic stroke symptoms.
      • High intracranial pressure (ICP) may lead to nausea, vomiting, altered consciousness, cranial nerve deficits, and posturing.
    • Cushing’s Triad: High blood pressure, low heart rate (bradycardia), and irregular respirations are signs of increased ICP.

    Diagnosis

    • Primary diagnostic tool: Non-contrast CT scan is crucial in detecting intracerebral hemorrhage and assessing for midline shift or hydrocephalus.
    • Additional imaging: CT angiography (CTA), MRI, and MR venography (MRV) can help identify vascular causes and cerebral venous sinus thrombosis.
    • Etiological investigation:
      • CBC to check for anemia and thrombocytopenia.
      • Comprehensive metabolic panel (CMP) for liver function.
      • Coagulation studies to assess PT/INR and PTT.
      • Urine drug screen for substances that may contribute to hemorrhage.
      • Blood cultures to evaluate for infective endocarditis.

    Treatment

    • Initial management:
      • Secure airway, especially in cases of declining consciousness due to large bleeds.
      • Mechanical ventilation may be necessary to maintain oxygenation and reduce brain metabolic demands.
    • Blood pressure control:
      • Target systolic blood pressure <160 mmHg using intravenous antihypertensives like nicardipine, labetalol, and enalapril.
      • Once stabilized, transition to oral antihypertensives.
    • Sedation: Utilize agents like propofol or midazolam for sedation and management of ICP.
    • Monitoring and further interventions: Monitor vital signs closely for changes in consciousness, respiratory function, and blood pressure.### Coagulopathy and Reversal Agents
    • It is essential toidentify if a coagulopathy exists, particularly in patients on anticoagulants.
    • Warfarin: Reversal involves administering 10 mg of IV vitamin K and prothrombin complex concentrate (PCC). Dosage for PCC varies with INR:
      • INR 1.5-1.9: 15 units/kg
      • INR 2-4: 25 units/kg
      • INR 4-6: 35 units/kg
      • INR >6: 50 units/kg
    • Heparin: If on a heparin infusion in the last 3 hours, administer protamine sulfate (max 50 mg).
    • Direct Oral Anticoagulants (DOACs): Apixaban and rivaroxaban can be reversed with PCC (20-50 units/kg). Idarucizumab is specific for dabigatran, a thrombin inhibitor.

    Management of Thrombolytics and Anti-platelet Agents

    • For patients on tPA, stop the infusion and administer tranexamic acid (TXA) 1 g bolus, possibly with cryoprecipitate.
    • Anti-platelet agents like aspirin and clopidogrel lack strong evidence for platelet transfusions, except when preparing for neurosurgical procedures.
    • DDAVP (desmopressin) can be considered in cases of anti-platelet therapy.

    Cerebral Edema and Intracranial Pressure (ICP) Management

    • Surgical Interventions: Decompressive craniectomy may be required if there is significant midline shift or herniation risk.
    • Evacuate Blood: Effective for infratentorial bleeds due to reduced space and risk of hydrocephalus.
    • External Ventricular Drain (EVD): Used to alleviate hydrocephalus when IVH occurs.
    • Medical Management: Administer hypertonic saline (3% or 23.4%) to draw excess fluid from brain tissue, aiming for sodium levels of 150-155 mEq/L. Mannitol (25% solution) is also used for fluid management.

    Seizure Management

    • Intracerebral hemorrhages near the cortex increase seizure risk due to epileptogenic foci.
    • Seizure types include focal seizures and generalized seizures, potentially leading to non-convulsive status epilepticus.
    • Anti-epileptic medications include phenytoin, fosphenytoin, valproate, levetiracetam, and sedative agents such as propofol and midazolam.

    Prevention of Intracerebral Hemorrhage (ICH)

    • Hypertension Management: Maximize antihypertensive medication to reduce the risk of recurrent bleeding from hypertensive events.
    • Anticoagulation: Indicated for cerebral venous sinus thrombosis to prevent clot expansion, despite the presence of bleeding.
    • Infective Endocarditis: Treat with broad-spectrum antibiotics and consider coiling for mycotic aneurysms to prevent bleeding.
    • Vascular Abnormalities: AVMs may require embolization to prevent hemorrhage from future pressure surges.

    Etiology and Pathophysiology of Intracerebral Hemorrhage

    • Hypertension is the leading cause of intracerebral hemorrhage, where sustained high blood pressure results in vessel rupture due to shear stress.
    • Intracerebral hemorrhages are classified into non-traumatic and traumatic, with a focus on non-traumatic causes.
    • Hypertensive bleeds commonly occur in specific brain regions, including:
      • Basal ganglia
      • Pons
      • Cerebellum
      • Less frequently in cortical or lobar areas (frontal, parietal, occipital, temporal lobes).
    • Cerebral Amyloid Angiopathy is prevalent in patients over 60, leading to cortical hemorrhages through amyloid protein deposition that weakens blood vessels.
    • Coagulopathies result from anticoagulant medications or liver dysfunction, impairing the body's clotting ability.
    • Hemorrhagic transformation may occur in ischemic strokes treated with tPA or exacerbated blood pressure, complicating already damaged areas.
    • Malignant tumors, particularly from lung, renal, melanoma, and papillary thyroid origins, can damage the blood-brain barrier, causing hemorrhage.
    • Cerebral Venous Sinus Thrombosis (CVST) arises from clots in brain veins, leading to hemorrhage due to pressure increase, often linked to hypercoagulable states.
    • Vascular abnormalities such as arteriovenous malformations (AVMs) and mycotic aneurysms are significant causes of intracerebral hemorrhage in younger demographics.

    Clinical Features

    • Symptoms include severe headaches, especially in cortical or lobar bleeds due to irritation of meningeal tissues.
    • Focal neurological deficits such as aphasia and weakness occur, similar to signs exhibited in ischemic strokes.
    • High intracranial pressure (ICP) symptoms may manifest as nausea, vomiting, altered consciousness, cranial nerve dysfunction, and abnormal posturing.
    • Cushing’s Triad consists of hypertension, bradycardia, and irregular breathing patterns, indicating elevated ICP.

    Diagnosis

    • Non-contrast CT scans are essential for detecting intracerebral hemorrhage and assessing complications like midline shift or hydrocephalus.
    • CT angiography (CTA), MRI, and MR venography (MRV) provide additional detail on vascular issues and cerebral venous sinus thrombosis.
    • Etiological investigations include a complete blood count (CBC) for anemia, comprehensive metabolic panel (CMP) for liver function, coagulation studies to examine PT/INR and PTT, urine drug screens for possible hemorrhagic contributing factors, and blood cultures for potential infective endocarditis.

    Treatment

    • Initial management requires securing the airway, especially if consciousness is compromised due to significant bleeding.
    • Management may include mechanical ventilation to maintain oxygenation and lower brain metabolic demand.
    • Blood pressure control is crucial, targeting a systolic blood pressure goal.
    • Protamine sulfate is administered for patients receiving heparin within three hours (maximum 50 mg).
    • Direct Oral Anticoagulants (DOACs) like apixaban and rivaroxaban can be reversed with prothrombin complex concentrate (PCC), while_idarucizumab_ is specific for dabigatran reversal.

    Management of Thrombolytics and Anti-platelet Agents

    • In patients receiving tPA, the infusion should be halted, and tranexamic acid (TXA) may be given alongside cryoprecipitate.
    • There is limited evidence supporting platelet transfusions for anti-platelet agents like aspirin and clopidogrel, except before neurosurgical interventions.
    • DDAVP (desmopressin) is an option for managing cases involving anti-platelet therapy.

    Cerebral Edema and Intracranial Pressure (ICP) Management

    • Surgical procedures such as decompressive craniectomy may become necessary to alleviate significant midline shifts or risks of herniation.
    • Blood evacuation is particularly effective for infratentorial hemorrhages due to the confined space and potential hydrocephalus.
    • External Ventricular Drain (EVD) is employed to relieve hydrocephalus following intraventricular hemorrhage (IVH).
    • Medical management may include administering hypertonic saline (3% or 23.4%) to extract excess brain fluid, targeting sodium levels of 150-155 mEq/L or using mannitol (25% solution) for fluid management.

    Seizure Management

    • Intracerebral hemorrhages occurring near the cortex present a heightened risk for seizures due to the formation of epileptogenic foci.
    • Seizure manifestations can include focal and generalized seizures, potentially progressing to non-convulsive status epilepticus.
    • Anti-epileptic medications such as phenytoin, fosphenytoin, valproate, levetiracetam, alongside sedatives like propofol or midazolam, may be utilized.

    Prevention of Intracerebral Hemorrhage (ICH)

    • Effective hypertension management is critical in preventing recurrent bleeding episodes due to hypertensive crises.
    • Anticoagulation might be necessary for managing cerebral venous sinus thrombosis in order to prevent the expansion of thrombus despite bleeding.
    • Treatment for infective endocarditis typically involves broad-spectrum antibiotics, with embolization as an option for preventing bleeding from mycotic aneurysms.
    • Vascular abnormalities such as AVMs may require embolization to prevent future hemorrhagic events from pressure surges.

    • In patients receiving tPA, the infusion should be halted, and tranexamic acid (TXA) may be given alongside cryoprecipitate.
    • There is limited evidence supporting platelet transfusions for anti-platelet agents like aspirin and clopidogrel, except before neurosurgical interventions.
    • DDAVP (desmopressin) is an option for managing cases involving anti-platelet therapy.

    Cerebral Edema and Intracranial Pressure (ICP) Management

    • Surgical procedures such as decompressive craniectomy may become necessary to alleviate significant midline shifts or risks of herniation.
    • Blood evacuation is particularly effective for infratentorial hemorrhages due to the confined space and potential hydrocephalus.
    • External Ventricular Drain (EVD) is employed to relieve hydrocephalus following intraventricular hemorrhage (IVH).
    • Medical management may include administering hypertonic saline (3% or 23.4%) to extract excess brain fluid, targeting sodium levels of 150-155 mEq/L or using mannitol (25% solution) for fluid management.

    Seizure Management

    • Intracerebral hemorrhages occurring near the cortex present a heightened risk for seizures due to the formation of epileptogenic foci.
    • Seizure manifestations can include focal and generalized seizures, potentially progressing to non-convulsive status epilepticus.
    • Anti-epileptic medications such as phenytoin, fosphenytoin, valproate, levetiracetam, alongside sedatives like propofol or midazolam, may be utilized.

    Prevention of Intracerebral Hemorrhage (ICH)

    • Effective hypertension management is critical in preventing recurrent bleeding episodes due to hypertensive crises.
    • Anticoagulation might be necessary for managing cerebral venous sinus thrombosis in order to prevent the expansion of thrombus despite bleeding.
    • Treatment for infective endocarditis typically involves broad-spectrum antibiotics, with embolization as an option for preventing bleeding from mycotic aneurysms.
    • Vascular abnormalities such as AVMs may require embolization to prevent future hemorrhagic events from pressure surges.

    Etiology and Pathophysiology of Intracerebral Hemorrhage

    • Hypertension is the leading cause of intracerebral hemorrhage, where sustained high blood pressure results in vessel rupture due to shear stress.
    • Intracerebral hemorrhages are classified into non-traumatic and traumatic, with a focus on non-traumatic causes.
    • Hypertensive bleeds commonly occur in specific brain regions, including:
      • Basal ganglia
      • Pons
      • Cerebellum
      • Less frequently in cortical or lobar areas (frontal, parietal, occipital, temporal lobes).
    • Cerebral Amyloid Angiopathy is prevalent in patients over 60, leading to cortical hemorrhages through amyloid protein deposition that weakens blood vessels.
    • Coagulopathies result from anticoagulant medications or liver dysfunction, impairing the body's clotting ability.
    • Hemorrhagic transformation may occur in ischemic strokes treated with tPA or exacerbated blood pressure, complicating already damaged areas.
    • Malignant tumors, particularly from lung, renal, melanoma, and papillary thyroid origins, can damage the blood-brain barrier, causing hemorrhage.
    • Cerebral Venous Sinus Thrombosis (CVST) arises from clots in brain veins, leading to hemorrhage due to pressure increase, often linked to hypercoagulable states.
    • Vascular abnormalities such as arteriovenous malformations (AVMs) and mycotic aneurysms are significant causes of intracerebral hemorrhage in younger demographics.

    Clinical Features

    • Symptoms include severe headaches, especially in cortical or lobar bleeds due to irritation of meningeal tissues.
    • Focal neurological deficits such as aphasia and weakness occur, similar to signs exhibited in ischemic strokes.
    • High intracranial pressure (ICP) symptoms may manifest as nausea, vomiting, altered consciousness, cranial nerve dysfunction, and abnormal posturing.
    • Cushing’s Triad consists of hypertension, bradycardia, and irregular breathing patterns, indicating elevated ICP.

    Diagnosis

    • Non-contrast CT scans are essential for detecting intracerebral hemorrhage and assessing complications like midline shift or hydrocephalus.
    • CT angiography (CTA), MRI, and MR venography (MRV) provide additional detail on vascular issues and cerebral venous sinus thrombosis.
    • Etiological investigations include a complete blood count (CBC) for anemia, comprehensive metabolic panel (CMP) for liver function, coagulation studies to examine PT/INR and PTT, urine drug screens for possible hemorrhagic contributing factors, and blood cultures for potential infective endocarditis.

    Treatment

    • Initial management requires securing the airway, especially if consciousness is compromised due to significant bleeding.
    • Management may include mechanical ventilation to maintain oxygenation and lower brain metabolic demand.
    • Blood pressure control is crucial, targeting a systolic blood pressure goal.
    • Protamine sulfate is administered for patients receiving heparin within three hours (maximum 50 mg).
    • Direct Oral Anticoagulants (DOACs) like apixaban and rivaroxaban can be reversed with prothrombin complex concentrate (PCC), while_idarucizumab_ is specific for dabigatran reversal.
